202414 · Concrete mix ratios are crucial for the right consistency, and the basic ingredients include aggregate, sand, cement powder, and water. Common ratios are 1-2-3 and 1-2-4, with higher sand content resulting in weaker concrete and more aggregate leading to increased strength. Concrete grades, such as M5, M10, and M15, indicate the …

20231116 · A slight reduction was observed in M20 – 0.42 QD & M20 – 0.43 mixes. M40 concrete mixes had the lowest water-cement ratios & higher cement quarry dust ratios & M40 mixes showed the lowest workability compared to other M20 & M30 QD mixes. M40 – 0.43 showed 5 mm slump & it was an 80% sharp decrease than M40 – 0.41 mix.

202231 · Quarry dust is one of the alternatives as it has some advantages over river sand such as better contribution to the strength of the cementitious material, better workability, lesser cement consumption and eco-friendly. The present study explored the feasibility of using quarry dust as fine aggregate in manufacturing cement blocks.
